How can I turn the debug bar on?

Have you also checked .htaccess (particularly in the public folder)?

If  you make any changes to some of these config files (including .env), you may also need to stop and restart the server to be sure they've been digested (though, I think the .htaccess in the public folder doesn't always seem to require this (?)).

I checked the .htaccess file but I really don't know what to change there. I tried to add to it (at the top) the line:

Code:

SetEnv CI_ENVIRONMENT development

But it didn't take ANY effect so I removed it.

And yes, I restarted Apache after all changes.

PS: I think it is not related to the issue, but... my pages are all rendered with "View Parser". I don't think the debugger is available only for whose render pages with plain View, is it?

Recovering the wasted time...
